2. Global perspectives of veterinary education All who work in veterinary education must recognize the breadth of their responsibilities. We are at a time in veterinary history where the profession must look how to meet a global standard for veterinary education and the global recognition of our basic qualification.

3. There is a societal expectation that a professional approach is being taken to managing food security and food safety, as well as the environment and biodiversity. — J Vet Med Educ. 2004,31(1):9-12.

7. General Introduction 免疫学简介

9. What is Immunity? Immunity, ability of an organism( 有机体 ) to resist disease by identifying and destroying foreign substances （ 异物 ） or organisms. Immunity is the ability of the body to resist or fight off infection （ 感染 ） and disease.

10. Immunity is a state of resistance （ 抵抗 ） to an agent, the pathogen （ 病原体 ）, that normally produces an infection. Pathogens include microorganisms （ 微生物 ） such as bacteria and viruses, as well as larger parasites （ 寄生虫 ）.

11. What is Immunology?

12. Immunology is the study of the ways in which the body defends itself from infectious agents and other foreign substances in its environment.

13. What is Immune System?

14. And, what’s more ★ Immune cells distributed in non-lymphoid tissues. 非淋巴组织中的免疫细胞 ★ Immune molecules Antibody( 抗体 ), Interleukin(IL, 白介素 ), complement( 补体 ).

15. Our Final Goals in the Study of Veterinary Immunology 兽医免疫学的基本任务 What are the components of immune system? How do they work? How do animals defend themselves? Why did animal fail to win the tug of war （ 拉锯战 ） sometimes? How to help them in favor of their health?

16. Two arms of immune system Innate immune system 天然 ( 固有 ) 免疫系统 Adaptive immune system 适应性免疫系统

17. Innate immunity Innate immunity is present in all normal individuals and operates on different infectious agents in the same way every time when the individual is exposed to the agents （致病因素）.

18. Innate immunity is also present at all times in normal individuals( 个体 ), modulated by physiological conditions( 生理条件 ). Innate immunity does NOT distinguish( 区分 ) among microorganisms of different species, and does NOT alter( 改变 ) in intensity( 强度 ) upon re-exposure( 再次暴露 ).

19. Cellular and molecular components of innate immune system Monocyte （单核细胞）, Macrophage （ MΦ ，巨噬细胞 ）, Dendritic cell （ DC, 树突细胞）, T lymphocyte, B lymphocyte （ T 细胞， B 细胞） Natural killer cell （ NK 细胞）, Mast cell （肥大细胞）, Neutrophil （中性粒细胞）, NKT Cell (NKT 细胞 ), Complement （补体）

26. The characteristics of the innate immunity include: ♠ response are non-specific( 非特异性的 ); ♠ there is no memory or lasting protective immunity; ♠ there is a limited repertoire( 储备 ) of recognition molecules( 识别分子 ); ♠ the responses are phylogenetically( 进化上 ) ancient.

27. Adaptive immunity Cellular and molecular components of the adaptive immune system ★ T cells, cell-mediated immune response cytokines, IL-4, IL-17, interferon(IFN-γ) ★ B cells, humoral immune response antibody

29. The adaptive immune system is quiescent( 安静的 ) until stimulated by a specific infection. This system is capable of exquisitely( 精细 ) distinguishing among microorganisms and significantly alters in its intensity and response time upon re-exposure.
